This paper identifies RCD1 as a PAR-binding protein that localizes to nuclear bodies and interacts with PPKs, which phosphorylate RCD1 and regulate its stability and function.

The paper identifies a novel role for GDP-L-fucose metabolism in stomatal closure through a genetic screen, revealing defects in fucose-related processes affect guard cell function.

The paper traces the evolutionary history of DUF26-containing proteins in land plants, showing their origin from secreted proteins and expansion through duplication mechanisms.

This study shows that methyl viologen induces ROS signaling in mitochondria of Arabidopsis, independent of light, and identifies mitochondrial Mn SOD and stress hormones as key factors.
